: After two fill coating of epoxy, I still have lots of areas where the
: fiberglass weave is still sitting up. The curing time is long, and as I
: brush down the runs, I think I'm removing alot of the fill. should I not
: worry about the runs and sand later? Does anyone have a good way to fill?

Worry about the runs early -- and remove them as best you can with a brush or squeegee while they are still liquid. Otherwise, try to remove them with a cabinet scraper the next day -- after the resin sets, but is still soft, or "green". It will be too soft to easily sand at this stage.

If you are using 6 ounce cloth or a cloth which has a deep or coarse weave it will take a few more coats to kill the weave than if you are using 3 or 4 ounce cloth. That is normal.

There is also an effect called "telegraphing" which you may be experiencing. The newly applied resin is following the curves of the previous layers, and not simply leveling out by flowing into the shallow hollows. In this case you have a nice thick layer of plastic building up and covering your glass fabric, but even with 5 or 6 coats, you still have a textured surface. This situation is simply solved by a light sanding. You want to knock off the high spots of resin without sanding so deeply that you actually get down to the cloth itself. A gentle touch and medium to fine grit sandpaper should do. You can do this with just a sanding block if you wish. Power sanding is faster, but not necessary. If you have two fill coats on and the resin has hardened enough to sand, you might sand it lightly before putting on a very thin coat.

Or, if you can sand it smooth without hitting any glass cloth, then you are done.Go straight to the varnishing.

hope this helps
